37 v .11 all wwm it may canoes-m: be 1 known that I,

' of the Emperor bi ing :it lilui hall, in Y county of Alle I and btei'e emisyh'zmm, have inszii ed certain new and useful Improvem nts in Traction Attachments for Vehicle'- li eals of which the followingis specification. v

This invention relates to certain new and useful improvements in tract-ion attachments for vehicle Wheels. 1 4 I An object, of the i. eenizion is to provide a ireoiion. device esoecielly designed for at- -liachmene to pneumatic tires of automobiles to i 'sure positive grip While passing on moody and sandy )l'OilLS.

e ith the above and other objects in View iiziahwill appear as the nature of the invention is better understood the same consists ihe novel oonstructioz combination, and arrangement of parzsto he hereinafter more fully described. and then claimed, reference being had to the accompanying drawing by like characters throughout the several views, and Wherein:--

Figure lie 21 side elevetionel View of a pneumatic tire, provided with an atiachment embodying myinvention." 2 is an plan View of -l;he seine. is an enlarged cross-sectionalView, and ig e is mi enlarged perspective view of the roed-eng'eg lire block.

Referring more particularly "so the drsm ing accompanying this application, the reference numeral 19 indicates a pneumatic tire oi the usual construction to be received on ithe rim section 11. i' ie said tire heihg reiained thereon by re iovaole rings 12 and locking band 33. li'he device as shown is applied to a tire of the pneumatic type but is readily adaptable "to solid tires or other forms of Wheels.

.ihiyoserl at each side of the Wheel pair of semi-circular plates 1% the sli ht-1y spnced at, their meecing ends. Each e1 o of the plat-es 2 provided with a log which new be formed integral therewith or secured thereto in any suitable mzinner as shown. A bolt 16 times opposiiely engaging the pla'tes 1* to llmli, me

- out to provide a curvature similar to or.

'l he inner feceof clock 19 which resis on' the tire 10 holh face of the said tire and strain upon he h. is therefore evenly distributed. This he? lowing out of the block provides emhriming arms 19* which are secured hehveen the plates 1% and the outer sides of the lire ehd the outer end 14? of the block is oppositel beveled to form a sharp vedge to engage the W road surf-nee li l'ien the several parts are; assembled inner the plates 14 rest 011* flange 11 of the rim 31.1 and the loe band 13 which relieves the strain on we fire 10. Iii tightening the'plates 14: by the bolts 16, the road-engaging blocks l-i brought into close-r relation with the iii-re 18 and a suhst antielly rigio structure "will re sole.- It will be seen from the Moore description and operation the device the; l o
